Avid Armor USV20 — Full Review
Overview of the Avid Armor USV20
The Avid Armor USV20 is a chamber vacuum sealer. The listing says it is made for wet foods and meat and has an 11.5-inch sealer bar. Because the whole bag sits inside the chamber, liquid does not get pulled toward the machine.
Key Features of the Avid Armor USV20
- Chamber design: Air is removed from the whole chamber at once, so wet foods can be sealed cleanly.
- Made for wet foods and meat: The listing title names wet foods and meat packing.
- 11.5-inch sealer bar: This is stated in the listing title.
- Compact build: The listing calls it compact for a chamber model.
- Sous vide use: A tight, air-free seal helps with water-bath cooking.
Strengths and Things to Know
- It can seal liquids, which an external sealer struggles with.
- Chamber machines need chamber-style pouches, not the textured rolls used by external sealers. Check which bags the maker recommends.
- Chamber machines are bulkier than handheld or compact external sealers. Plan counter or shelf space.
- Check the product page for what is included in the box.

How They Compare in Real Use
The chamber sealer vs vacuum sealer choice comes down to what you seal. The chamber design wins with soups, sauces and marinated meat, because liquid stays in the bag. The external FoodSaver wins on size and ease for dry goods, cheese and leftovers.
Bags are another point. Chamber pouches and external-sealer bags are different products. Check which bags each machine uses before you buy, and plan for the ongoing bag cost.

Food safety tip: Oregon State University Extension says vacuum packing is not a substitute for refrigerating or freezing food that would otherwise need it. Store low-acid vacuum-packed foods at 38 to 40°F.
